Report

What did you do?

Really just run the above command on current supported dynamic packager.

What did you expect to happen?

A dynamic framework should have been created

What happened instead?

    Undefined symbols for architecture armv7s:

    ld: symbol(s) not found for architecture armv7s
    clang: error: linker command failed with exit code 1 (use -v to see invocation)

Solution

For now, I just skip the <exception> file symbol and worked. Can someone tell me how to fix it more safely?
